In the version of tapatalk I have, Pro???, I can select multiple posts by clicking on them (they get a blue background), then I can hit the 'quote' image (at the top of the screen) and they all appear in a post I can edit.
I thought someone wanted this feature a few months ago and I just stumbled upon it. I do have a paid version of tapatalk.
It also works across multiple pages in the same thread.
